Supergirl

Like Brandon Routh’s Superman before her on this list, Helen Slater’s Supergirl really did look the part. Unfortunately, the 1984 movie was absolutely abysmal on the whole.
It was absolute nonsense, and Slater didn’t really do herself any favors in the role. Sure, she was cheery and likeable enough, but her characterization was too inconsistent and her actual acting was amateurish, to say the least.
Even the movie’s links to the Christopher Reeve series of Superman movies – of which it was a spin-off – couldn’t prevent it from completely flopping at the box office. Slater’s portrayal of the titular character really didn’t help matters on that front, even though her look was nailed.
